“…Most trichomes observed in M. lewisii are bicellular or tricellular in the glandular head, while M. tilingii have primarily tetracellular heads, consistent with descriptions by Schepf and Busch (1976). Other montane species, Solanum lycoperiscum and S. tuberosum, also have type VI glandular trichomes with tetracellular heads (Kang et al, 2010; Bergau et al, 2015; Cho et al, 2017). The presence of a cuticle protecting the secretions in the subcuticular space of the trichomes that we observed in M. lewisii and M. tilingii was also identified in S. lycoperiscum and S. tuberosum , suggesting this structure could function to sequester and store the secretions until a physical disturbance, such as water droplets or insect visitation, causes the cuticle to rupture (Tissier et al, 2017).…”

11Two distantly-related North American montane monkeyflower species, Mimulus lewisii and 12 Mimulus tilingii, possess glandular trichomes. In this study, we characterized the 13 morphological and histochemical features of these glandular trichomes. For each species, we 14 used traditional light microscopy and scanning electron microscopy (SEM) to examine 15 morphological characteristics, and determined the main components of the secretory products 16 using histochemical and thin layer chromatography (TLC) staining techniques. We identified 17 type VI glandular trichomes on leaf surfaces in both species of monkeyflowers. These 18 trichomes exhibited stalk-cell lengths and head-cell counts that varied across adaxial and 19 abaxial leaf surfaces, stems, and sepals. Both species contained secretory products within the 20 cuticle of the trichome head, which releases the subcuticular metabolites when ruptured. 21 Histochemical tests in both M. lewisii and M. tilingii confirmed that secretions contained 22 lipids and polysaccharides. TLC plate staining indicated the presence of UV active 23 compounds with polyalcohols, lipids, and amines. The common morphology and chemistry 24 of the glandular trichomes suggests an analogous response to similar environmental 25 conditions in these evolutionary distant montane monkeyflowers. 26 27

“…Based on trichome morphology, they can be divided into single-cell and multi-cell, branched or unbranched. Moreover, depending on the presence of glandular heads, trichome types of the tomato (Solanum lycopersicum) species, a native to the Solanaceae family, are divided into two distinct groups: glandular (types I, IV, VI, and VII) and non-glandular (types II, III, and V) [29]. Type I trichomes are characterized by their multicellular base, long multicellular stalk, and their small glandular head.…”

“…Type VI trichomes comprise a four-celled glandular head on a short multicellular stalk. Type VII trichomes consist of a short unicellular stalk and an eight-celled head [29]. Non-glandular type II and III trichomes are similar in shape, but differ in the nature of their base, which is multicellular or unicellular, respectively.…”

“…Non-glandular type II and III trichomes are similar in shape, but differ in the nature of their base, which is multicellular or unicellular, respectively. Type V trichomes are shorter than type II and III trichomes, and have a unicellular base [29,30]. Four hair types of potato are very similar to tomato non-glandular (II and V) and glandular (VI and VII) trichomes.…”

“…Like the cultivated potato species, the 17 wild potato species also possess four different trichome types, although the density of each trichome type displays considerable variation among the wild species. Cho et al [29] divided the 17 examined species into four groups based on trichome density and type. Group I have more glandular trichomes compared to those in other species; group II have more non-glandular trichomes on both leaf surfaces; group III contains only one species, which has the highest density of abaxial leaf-surface non-glandular trichomes; and group IV species display non-glandular and glandular trichome density at an intermediate or lesser level compared to species in other groups.…”

Leaf wettability has an impact on a plant’s ability to retain water on its leaf surface, which in turn has many environmental consequences. In the case of the potato leaf (Solanum tuberosum L.), water on the leaf surface may contribute to the development of a fungal disease. If fungal disease is caused, this may reduce the size of potato harvests, which contribute significantly to meeting global food demand. The aim of this study was to assess the leaf wettability of five potato cultivars (i.e., Bryza, Lady Claire, Rudawa, Russet Burbank, Sweet Caroline) in the context of its direct and indirect impact on potato yield. Leaf wettability was assessed on the basis of contact angle measurements using a sessile drop method with an optical goniometer. For Bryza and Rudawa cultivars, which showed, respectively, the highest and the lowest contact angle values, light microscopy as well as scanning electron microscopy analyses were performed. The results of the contact angle measurements and microscopic image analyses of the potato leaf surfaces indicated that the level of wettability was closely related to the type of trichomes on the leaf and their density. Therefore, higher resistance of the Rudawa cultivar to biotic stress conditions could be the result of the presence of two glandular trichome types (VI and VII), which produce and secrete metabolites containing various sticky and/or toxic chemicals that may poison or repel herbivores.
